Hello all, new to the forum. Have owned my 997 for over a year now and still loving it. Have had an issue with my battery being drained over night and have diagnosed it as far as the ask amplifier. With this disconnected, the battery isn't drained. In wondering if its just a case of buying a new one or if its my CD player unit supplying it to stay on.can anyone help? In after which colour wire is the supply from the CD player to the amp to power it up to see if this has 12v on it before buying a new amp

Thanks

 

What year and make is your 997?

For a 2006 at the connector on the ASK amplifier, pin A1 Red w/Brown is power, pin A2 Brown w/Brown is ground, and pin A11 Black w/Red is the wakeup signal from the PCM (radio). The connector should have the pin numbers on the plastic housing somewhere. Power on A1 goes directly to the fuse panel in the driver's footwell area, row D fuse 10.

Bose amps are similar, power red/brown on A1, ground brown/brown on A2. But the wakeup signal is on another connector white/red on B5. The PCM might also send wakeup commands to the Bose amp via the fiber optic MOST network on connector C (orange fiber "wires").

 

Its 2006. Yes I have 12v from fuse d10 onto the red/brown perminently. I will have to test that I loose the 12v on the black/red when sleep. If I do, I can assume the amp is sticking on or draining the power. Speakers or anything else from the amp couldn't drain the battery?

Thanks

Right, done a little bit of testing and nothing looks unusual :/

There is 12v on the red/brown perminently. Nothing on the black/red until I insert my key and the radio comes on and there is 12v on it then.

I have removed the amp and there isn't any drain on it when giving it 12v between red/brown and brown. Only when 12v is connected to pin black/red I get a current on the red/brown.

What is the wiring for the speaker? They give all sorts of resistance readings ranging from 5 ohms to k ohms? Could a speaker be at fault? Is there any other wiring to the amp as to me it all tests out OK

Thanks

 

Can't see it being a loudspeaker fwiw. How old is the battery?

 

The battery is brand new and no different. With the amp out the car and the fuse still in, its fine and doesn't drain the battery.

 

Speaker is a passive device and won't drain a battery.
As for the amp, it would have to actually have to be turned on and drawing current.
Just meter between battery and amp to see if it's drawing current.
Typically, stand by current should be less that 500ma.

 

Less than 50mA. Typically 45mA.
